Domain 1: Accounting Information Systems (AIS)
Fundamentals
Q1. Which component of an accounting information system is primarily
responsible for transforming raw financial data into meaningful reports for
decision makers?
A. Input component
B. Processing component
C. Storage component
D. Output component
Correct Answer: B
Rationale: The processing component includes classifying, summarizing, and calculating
data to transform raw financial data into meaningful reports. The output component
presents the information, but processing is where the transformation occurs .
Q2. In a relational database, which element is used to uniquely identify each
record in a table?
, A. Foreign key
B. Primary key
C. Composite key
D. Secondary key
Correct Answer: B
Rationale: A primary key uniquely identifies each record in a table, ensuring each row is
distinct. Foreign keys link tables together .
Q3. Which type of information system is most commonly used by middle
managers to monitor performance and make tactical decisions?
A. Transaction Processing System (TPS)
B. Management Information System (MIS)
C. Decision Support System (DSS)
D. Executive Support System (ESS)
Correct Answer: B
Rationale: Management Information Systems provide summarized reports for
monitoring performance and supporting tactical decisions by middle managers .
Q4. Which type of database relationship exists when one record in a table can
relate to many records in another table?
A. One-to-one
B. One-to-many
, C. Many-to-many
D. Zero-to-many
Correct Answer: B
Rationale: A one-to-many relationship is the most common type, where a single record
in one table can relate to multiple records in another table .
Q5. What is a foreign key?
A. A security clearance token for database access
B. An attribute in one table that is a primary key in another table, used to link
tables
C. A decryption key for cloud-based backups
D. The primary indexed field in a master file
Correct Answer: B
Rationale: Foreign keys act as references to primary keys in separate tables, maintaining
referential integrity across the relational database framework .
Q6. Which of the following best describes the primary purpose of an Accounting

A. To automate human resource hiring pipelines
B. To collect, record, store, and process accounting data to produce information
for decision-makers
C. To manage the physical manufacturing of factory goods
, D. To host external marketing campaigns
Correct Answer: B
Rationale: An AIS is specifically designed to transform raw financial and operational
data into meaningful information that internal and external stakeholders use to make
strategic decisions .
Q7. In a database, which type of relationship exists when many records in one
table relate to many records in another table?
A. One-to-one
B. One-to-many
C. Many-to-many
D. Direct relationship
Correct Answer: C
Rationale: A many-to-many relationship requires a junction table to properly connect
the records between tables .
Q8. In an Entity-Relationship (ER) diagram, what does cardinality represent?
A. The processing speed of the database server
B. The numeric formatting used in currency fields
C. The nature of the relationship between two entities, expressing the maximum
and minimum number of records that can be linked
D. The security classification code of a database table
